BAILROAD-CROTSSIQNG GATE neously.

With the foregoing and other objects in View as will'appear as the description proceeds, the invention consists ofthe novel con struction, combination and arrangement. of co-operating elements as hereinafter more specifically set forth, claimed and shown in 'the' accompanying drawings forming a part of the present application, in which Fig. 1 is a diagrammatical view, showing the gates in closed position with their flexible connection extending to the operating tower.

Fig. .2 is a schematic view, showing a connection between the respective operating means and the tower operating means.

Fig. 3 is a top plan view of the operating means for the gates. I

F" g. 4 is a sectional view taken on the line 44; of Fig. 3.

Like numerals of'reference designate corresponding parts throughout the different V1 BWS.

A is the railroad'bed, is the roadway and C is the pedestrian path'or sidewalk. E, F, Jr and H are housings. In the following description I have shown in Figs. 3 and 4 the 7 housing G, the housings E, F and H being of a similar type and having corresponding operating means therein.

Each housing is an enclosure 5 with a base 6, preferably formed of reinforced concrete, steel or the like If desirous a top may be placed thereover with suitable slots therein to permit the bars of the gates to be operated ther'ethrough.

I7 is the main shaft supported in suitable hearings on the opposite sides of the housing 5. Mounted on the shaft 7 is a sprocket gear 8 over which the sprocket chain 9 is trained. The sprocket gear 8 is keyed to the shaft 7 by means of the key 10. 11 and 12 are castings having annular openings therethrough,

which castings are fitted on and keyed to the Application filed April 3, 1930. Serial No. 441,273.

shaft 7 at opposite sides of the sprocket gear 8. The inner ends of the side bars 14, which. form part ofthe gate 15, are suitably bolted at their inner ends to the respective castings 11 and 12. Ifdesirous, the castings lland 12 may be heavier on the innerside to act as a counterbalance weight. 16 is the pedestrian gate provided with a removable facer plate 17 on its under side adjacent its inner end. The end wall of the housing 5 is provided with a facer plate 18 over which the 'facer plate 17 and thejpedestrian gate is adapted to be slidably moved. The inner endof the pedes-,v trian gate ishingedl-y connected to the inner end of one of the side bars 14 by means of the hinge '19. The end of this sidebar 14: d

and the end of the pedestrian gate 16 is notched to permit the cable 20 to extend up therebetween whenthe gates are in closed position. This cable 20 has its upper end connected around the pin of the hinge 19 and its lower end connected to the counterbalance weight 21. a 22 and 23 are shafts suitably supported in bearings on the opposite sides of the housing 5. Mounted on the shaft 22 is the idler pulley 24-. Mounted on the shaft 23 is the idler pulley 25. Connected to the outer end of the sprocket chain 9, I provide a flexible cable '26, which extends down, and around the idler pulley 2 1, through a suitable opening 27 in, the side of the housing G and through a conduit 28 to the. tower 29. The inner end of the sprocket chain 9 has connected thereto, a flexible cable 30, which extends down and around the idler pulley 25, through a suitable opening 31 in the housing G, through a suitable conduit 32 under the road bed to the housing F, around one portion of the idler pulley 33, around the sprocket gear 8, back around the other portion of the idler pulley 33, back through the conduit 32, through the housing G, through the conduit 28, up to the tower 29, around the operating drum 3 1 in the tower and has its end connected to the flexible cable 26 to form an endless interconnecting flexible control member between the sprocket gears 8, 8 and the operating drum 34. The flexible cable 30, where it passes around the sprocket gear 8,

will be provided with a sprocket chain similar to the sprocket chain 9, so as to transmit positive rotary movement to the sprocket gear 8 The housings E and H are provided with similar operating means and an end-' less interconnecting flexible control member 26 for operating the same, which'is trained over a drum 34; correspondingto the drum 3a in the tower 29. 'Thus, the gates oper-. ating from the housings E and H will be j controlled by .onedrum, while the gates oper-f ated from the housings F and G will be controlled separately by another drum.

Thev foregoing specification and annexed drawings disclose the preferred embodiment of my invention, but it is to be understood that minor changes may be resorted to in the commercial adaptation of myinvention without departing from the scopeof the in- Q vention as hereinafter claimed. o

:What I'claimasnew; is: 3 V

railroad-crossing gate comprising a set of; four housings, one positioned at each respective corner of the intersection between a roadway and a railroad bed; each ofsaid housings comprising side walls, end walls I and a bELSGtQEICh' of said housings having a a shaft suitably mounted in bearings supported in the sidewallsof said housing; an operating gear keyed on saidshaft; counterbal- 'ance weights keyed on said shaft road gates the ends of the side bars of said. road gates being connected to I said counterbalance v weights; a pedestrian gate, having a facer 35 7 plate on itsunder side adjacent its inner end; 7 av faCer-plateon'the top of the end'wall over which said pedestrian gate facer plate is adaptedto move; the end of said pedestrian gate being hingedly connected to the end of 40 one of the side bars of said road gate; a

counterbalance weight suspended from the pin of said hinge; flexible connections beone side of the road with the, gears in the respective housings on the opposite side of the road and said respective flexible connections being trained over separate operating means, in an operating tower, for operating said connections.
